Topic: $50 robot help with atmega168a (Read 1126 times)

hi, this is my first robot and when i started i decided to do all the uart modifications to the mcu, however after the uart modifications the robot's two primary drive servos were acting a little funky... they would start and stop continuously creating a vibrating effect through-out the whole chassis. after that, i just wiped the chip and added the original code with the appropriate modifications and now the robot just does not function at all. i have a good feeling this has something to do with the programming...

well with that last post, it appears that i have turned off one of the clocksetting fuses. however ponyprog is giving me an error that it cannot read the chip itself. when i say locked up, i mean i cannot read or write anymore data to the chip, and when i hit the ignore on the read it shows me a hex file full of nothing but 0's. when i open up the security bits all the boxes are checked showing me that all the fuses are connected. i will try what that post said and see if i can't fix it that way... and i thought i was going to have something interesting to smash too... dang.

hey, i found this interesting forum on a "high voltage" programmer. comes with a wiring schematic and everything. it is designed for the atmega168, but apparently somebody was using it to reset their atmega328p's. the link is below.
